Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional A514 Gr E quenched and tempered steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of A514 Gr E quenched and tempered steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
GJB/1496A-2000 this standard uses and manufactures 28Cr2Mo steel plates with thicknesses of 10, 12, 15, 20, 25, 30mm for armored vehicles, and 26SiMnMo steel plates with thicknesses of 5, 6, 8, 10, 12, 15, 20mm and thicknesses. 28Cr2Mo is armored bullet-proof steel, code-named GY4. It is the main protective device on the tank. It needs to have high elasticity resistance. It also needs to have good processing technology and welding performance to meet the requirements of the tank manufacturing industry.
40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. A514 Gr E quenched and tempered steel, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.
Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, A514 Gr E quenched and tempered steel included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.
The difference of chemical composition between A514 Gr E quenched and tempered steel, Q420D steel and Q460D steel: Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015. The difference of mechanical properties between A514 Gr E quenched and tempered steel, Q420D steel and Q460D steel: The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.
